Full Discussion: Get letter from number and assign to a variable
Top Forums Shell Programming and Scripting Get letter from number and assign to a variable Post 302565416 by Paragon1970 on Monday 17th of October 2011 09:58:23 PM

You could try it this way....

Code:
LetterNumber=10
for i in $(seq 1 ${LetterNumber})
do    
   printf -v letter "\x$(printf %x $((${LetterNumber}+64)))"
   echo ${letter}
done

Personally, I would more than likely use perl as it is more cross platform friendly. For example the -v switch does not appear to be available in Solaris10 bash printf command, which in itself is a little weird as printf is internal to bash, so I would have thought it should be pretty much the same across bash instances on various OS but hey ho....

Regards,
SRG

seq

SEQ(1)							    BSD General Commands Manual 						    SEQ(1)

NAME

     seq -- print sequences of numbers

SYNOPSIS

     seq [-w] [-f format] [-s string] [-t string] [first [incr]] last

DESCRIPTION

     The seq utility prints a sequence of numbers, one per line (default), from first (default 1), to near last as possible, in increments of incr
     (default 1).  When first is larger than last the default incr is -1.

     All numbers are interpreted as floating point.

     Normally integer values are printed as decimal integers.

     The seq utility accepts the following options:

     -f format	   Use a printf(3) style format to print each number.  Only the E, e, f, G, g, and % conversion characters are valid, along with
		   any optional flags and an optional numeric minimum field width or precision.  The format can contain character escape sequences
		   in backslash notation as defined in ANSI X3.159-1989 (``ANSI C89'').  The default is %g.

     -s string	   Use string to separate numbers.  The string can contain character escape sequences in backslash notation as defined in ANSI
		   X3.159-1989 (``ANSI C89'').	The default is 
.

     -t string	   Use string to terminate sequence of numbers.  The string can contain character escape sequences in backslash notation as
		   defined in ANSI X3.159-1989 (``ANSI C89'').	This option is useful when the default separator does not contain a 
.

     -w 	   Equalize the widths of all numbers by padding with zeros as necessary.  This option has no effect with the -f option.  If any
		   sequence numbers will be printed in exponential notation, the default conversion is changed to %e.

     The seq utility exits 0 on success and non-zero if an error occurs.

EXAMPLES

	   # seq 1 3
	   1
	   2
	   3

	   # seq 3 1
	   3
	   2
	   1

	   # seq -w 0 .05 .1
	   0.00
	   0.05
	   0.10

SEE ALSO

     jot(1), printf(1), printf(3)

HISTORY

     The seq command first appeared in Plan 9 from Bell Labs.  A seq command appeared in NetBSD 3.0, and ported to FreeBSD 9.0.  This command was
     based on the command of the same name in Plan 9 from Bell Labs and the GNU core utilities.  The GNU seq command first appeared in the 1.13
     shell utilities release.

BUGS

     The -w option does not handle the transition from pure floating point to exponent representation very well.  The seq command is not bug for
     bug compatible with the Plan 9 from Bell Labs or GNU versions of seq.
